Application filed June22, 1911. Serial No. 634,679.

To all whom t may concern:

Be it known that I, ,WALTER J BEATTIE, a citizen of the United States, residing ,at Cohoes, `count-y of Albany, and Stat-e of New York, have invented certain new and useful Improvements in Operating Mechanism for Foldingl/Iachines, of whiclrthe following is ya specification.

.The invention krelates to such improvements and consists ofthe novel construction ,and combination ,of parts hereinafter described and subsequently claimed.

vReference .may be hadto the accompanying drawings, andthe Nreference characters marked thereon, which form a partvof this specification. Similar characters refer to similary parts in the several figures therein.

Figure 1 of the drawings is a view partly in side elevation and partly in verticalsection` taken on` the broken line 1--1 in Fig. 2, of `a folding-machine provided with myimproved operating-mechanism. Fig. 2 is a view in front elevation ofthe same, with the templet-support broken away. Fig. 3 is a .view inrear elevation of the same. Fig. ,4; is a plan view of the table and infolders Vof the machine. Fig. 5 is a horizontal section taken on the broken line 5 5 in Fig. 1, showing a -plan view of the treadle.

The principal object of my invention is to provide operating-mechanism for the foldingand` pressing elements of a machine for folding cloth-blanks such as are used in the manufacture of shirts, collars and cuffs and thelike, and more particularly to provide such mechanism in a form such thatthe successive movements of the folding and pressing elements are accomplished in the lproper order by the movement of a single element by foot or other power.

'Another object of the invention is to provide operating-mechanism of the character A described, adapted to cooperate interchangeably with the folding and pressing elements fordierent styles of blank.

Referringto'the drawings wherein the invention isshown in preferred form, 1, represents the frame ofthe machine which supports the operating-mechanism; and, 2, is a bed or table which supports the folding and pressing elements. Said table is removably mounted upon the frame by means of bolts,

`3, permittinga tablel supporting the folding kand pressing elements for one-formof blank to beremved'from the-frame,anda table supporting the folding and pressing elements for another form of blank to be substituted therefor' vat will, the operatingmechanism mounted upon the frame being adapted to coperate interchangeably with the folding and pressing elements for diferentvstyles of blank.

The folding and pressing elements comprise a templet, 4;, which may be of any known form ;l infolders, 5, movable inwardly and outwardly upon the bed to cooperate with the templet; and a vertically movable bed, 6, upon which the blank is placed to be folded, vand which is adapted to be moved upward to press the fol ded edge of the blank between said lbed and thel infolders, 5, upward movement of the infolders being limited by a'stop-bar, 7, overhanging said infolders. The infolders are guided intheir inward and outward movements by pivoted links, .8, in the usual manner, and, they are .adapted to .be moved inwardlyy and outwardly by means of crank-disks, 9, in fixed relation to the respective beveled gears 10.

A templet is shown mounted upon a lever, l1, pivotally mounted upon the bedor. table,

which lever is adapted to be automatically rocked to raise the templet, as by a counterweight l2. The lever isadapted to be operated against the force of the counterweight ,v

.be connected with a vertically movablerod,

19, whereby said'bed is at certain times forced upwardly to perform the pressing operation. yThe rod, 19, is shown screwthreaded into .the vertically movable bed,

lpermitting of its ready connection therevwith and separation therefrom as desired.

rlhe .,link, `13, 'can be readily disconnected from the templet-carrying lever, 11,-by unscrewing the link from the'yoke, 70, and in like manner said link can be connected with a similar yoke on the die-carrying lever carico redbylaft'op orv bedfadapte'd for dielnt foot or otherpower.

Athe. two branches 21 and 22. The'longer branch, 22, of the treadle-lever is connected by a link, 23, with a pawl-carrying member, 24, pivotally mounted upon the cross-shaft, 25, upon .which cross-'shaft is fixed a gearwheel, 26, and a ratchet, 27, adapted to be engaged bythe pawl, 28, mounted upon said pawl-carrier, 24, and the parts are so proportioned and arranged that a complete Vdownward movement of the treadle-lever,

20, will cause a one-sixth rotation of the gear, 26, through said pawl and ratchet.

y The gear, 26, meshes with a pinion, 29, which is rotatively mounted in fixed relatio-n withV a geaswheel, 30, adapted to mesh with a pinion', 3l, fixed upon the cam-shaft 32. The several gears/and pinlonsv are so proportioned that a one-sixth rotation of the gear,

26, will cause a complete rotation of the pinion 31. Fixed upon'the cam-shaft, 32,

are two cams 33 and 34. f The cam, 33, i's

adapted to engage a cam-followei,35, on the end of a rocker-arm,l36, fixed upon the rockshaft, 37 andthe cam, 34, is adapted to engage a cam-follower, 38, on a lever, 39, pivotally mounted upon said rock-shaft 37.

From a comparison of Fig. 1 with Figs.V 2 and 3, it will be understood that as shown in Fig. 1, cam, 34,'and lever, 39, are some- -what in rear of the cam, 33, and rocker-arm 36. As vthe cams, 33 and 34, move in the directio-n of the arrow, 40, in Fig.1,it will be seen that the initial movement of the cams causes the abrupt rise on ythe cam, 34,

to engage the follower, 38, to-quickly raise the lever, 39, thereby forcing upward-the link, 13, and causing the templet, 4, to be broughtv quickly down upon the bed or upon a` blank placed upon the bed, after which said lever, 39, is heldin a raised position by a rest konrsaid cam, 34, until the cam-follower, 35, has been engaged by the carn,33,

Y and raised sufficiently to cause an inward movement of the infolders over the edgesof the templet suflicient to .hold the templet down-when released from-the influence of the link 13. g abruptly, permitting the arm, 36,A to fall quickly to Vpermit a return movement of the infolders upon lthe completionof the fold-` ing v'and pressing operatlons. The rocker- Y The cam, 33, V,terminatesarm, 36, lcauses operation of the toothed rack, 16, by means of an arm, 41,'iXed upon the rock-shaft, 37, and connected by link,

42, with an arm, 43, on the rear rock-shaft,

17, said arm, 41, being Vadapted to directly engage a rocker-arm, 44, fixed upon the frontV rock-shaft, 17 said rocker-arm, 44being provided with a friction-roller, 45, inl

the path of said arm 41. A returnmovement of theinfolderswhen released is accomplished by means of a coil-spring, 46, which connects together two arms, 47 tand 48, on the respective shafts- 17. The rod, 19, is pivotally connected at its lowerend at, 50, with a lever, 51, fulcrumed at, 52, upon the frame of the machine, and having its front end in the path of the shorter rearward-ly projecting member, 21, of the treadle-lever,

wherebythe final power-induced movement of the treadle-lever will cause said lever, 51,

to be raised and the rod, 19, to be forced upward toraise the bed, 6, to perform the pressing operation upon the folded blank.

The treadle, 20, is normally held raised by ,l

the spring 53. Y Y

As a means for preventing inertia of the moving parts from carrying the gear, 26, beyond a one-sixth rotation at each'operation of the treadle, I have' shown the hub,- `54, of said gear, 26, formed with siX symmetrically disposed notches,55, one of which is adapte edito receive a spring-actuated dog, y56, luponv the completion of each one-sixth rotation of thegear 26. The dog, 56, is in'theform of aslide mounted in thebarrel, 57, and has a pin, 58, projectingl through a lslot .in rthe side of the'barrel into the path of Ya 'camshaped member, 59, on the upper end of a rod, 60, which is connectedat, 61, with the longer rearward member,22v ofthe treadlelever. The Acam-shaped member, 59, plays through a guide-plate, 62, mounted upon the barrel, 57, and'is adapted when the trea'dle is in raised position to hold the dog, 56, out of engagement with the hub, 54, of the gear wheel, 26, but as soon as the treadleis delos f pressed the cam-shaped member, 159, is moved upwardreleasing thepin, 58, and permitting the dog to be forced by its actuating spring, '5

63, against the face of the hub, 54, whereby it is adapted to enter the neXt notch, 55, which is brought opposite said dog,and having entered said notch the dog acts as positive stop for thergear 26. `As the treadle is restored toelevated position, the cam-shaped member, 59, is again brought into 'engagement with the-pin,'58,'to withdraw the dog, 56, fromrthe notch, 55, leaving the gear, 26,

'free to be againpartially ',rotated.- .It-will.

thus beV seen .thata-f successive downward movement of the ltreadle 'operates succesi sively in the proper-order, TS'U the'tenflflet 4, to bring the same downy upon'` the blank on the bed of the-machine; secondly, to move the infolders nfwardfto mturnthe ledges lof ,iso

the blank over the templet in the usual manner; and thirdly, to raise the bed to press the folded blank.

I do not wish to be limited to any particular type of folding and pressing elements, as, for certain purposes of the invention these may be of any known ty'pe.

The return movement of the lever, 51, which may be termed the pressing-lever, is limited by a screw, 65, which is adjustable in a bracket, 66, in the path of the rear of said lever.
